COMPOUNDS, IN PARTICULAR BASED ON TITANIUM, VANADIUM, NIOBIUM, REDUCED, PARTICULARLY OF THE TYPE TITANITES AND THEIR PREPARATION. |
| abstract |
The present invention relates to a compound based on a first element, in particular titanium, vanadium or niobium, of a rare earth and oxygen and in which the first element at least partially exhibits an oxidation number. less than its maximum oxidation number. The preparation process consists in calcining under a reducing atmosphere a starting compound comprising said first element in a higher oxidation state than that in which it is present in the compound prepared. PrTiO3 is thus prepared, for example, from Pr2 Ti2 O7. Compounds corresponding to solid solutions either of the first element or of rare earth can be obtained more generally in a perovskite structure of the PrTiO3 type. |
